This invention relates to pipelayout gauges and more particularlyto a portable. gaugemounte able on. a pipe to provide a guide'for scribing a cutting line on a pipe at a predetermined angleto the longitudinal center line oi the pipe.

It is among the obiectsof the imzention to provide an improved portable gauge assembly which can be conveniently carried in a mechanids tool box and set for use on a pipe" in situwithout first. disconnecting or removing the pipe, which can be set tovarizousangl'es; and. provides a firm. guide for scribing a linearound the pipe so that: thepipetcan; be cut to position. its out edge in a plane disposed at a predetermined angle to: the longitudinal center line of the pipe,- which is easy toadjustand to set up on a pipe and is accurate in use; which. can be used onpipes of different sizes within a predetermined size range; and which is simple and durable in construction, economical to manuiiacture,v and easy to use in a. manner to'obtain' accurate results.

Other objects and advantages will. become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawings. wherein? Figure I is a side elevational view or a pipe scribing gauge illustrative of the invention shown in operative position on a length of pipe;

With continued reference to the drawings, the gauge comprises a base block Whaving on one side a concave surface: H including two plane surfaces: which. intersect along the longitudinal center line of the corresponding oi? the block and are disposed at an obtuse angle to each other so that the transverse cross sectional? shape of. this side of the block is that of a shallow, inverted line The opposite side or the block is convex and comprises two plane surfaces respectively paraller to the surfacesconstitiitmg the concave side of the. block and a stem time H? of polygonal, preferably square, cross secticnafshape, projects from convex side ofthe hlock'atone of the latter substantially perpendicular to the length of the concave-surface H; p

A protractorsca-le 2B is provided on the scale plate 2'! around the arcuatelyf shaped concave edge of the Iattcrands' a pointer 21' is provided on the plate 213 toind-icate the angular relationship between the stem if and. the-"standard W. r

The center line of the stem H issubstantiallytangent to the peripheries of the circular plate pol-times 22 and 23: and'the extends from the bracket M the section-Z82 upon arm in stone mid a clamp 3| which engages the stem 24 and at its other end with a ring formation 32 which surrounds the pipe section 28.

The clamp 3| comprises two flat plates 33 and 34 disposed in side by side relationship and having intermediate their length offset and transversely extending formations 35 and 56 respectively which together provide a sleeve slidably receiving the stem 24. At one side of the sleeve provided wee formations 3.5'anjd136 the two plates are'provided withregisterin'g'apertures and a screw 31 extends through these apertures and v is provided with a wing nut 38 for clamping the v clip in adjusted position on the stem 24= At the side of the sleeve provided by the formations and 36 opposite the screw 31 the plates are provided with outwardly extended portionsfifi and-.

tical opening ;4l *for receiving the pipe section I tobemarked.

This ring formation-is divided-into two parts along the minor axis of the elliptical opening 4i and the two parts are providedattheir ends with outwardly projecting lugs, as indicated at 42 and 43 in Figures 6 and 7,,whichexte'nd perpendicularly from the side of the .web' portions of the channel'shaped ring members at the inneror concave sides of'these. members and are "superimposed at the respectively opposite-sides of'the ring formations. .The'.'lugs' at. the ends/of .the portion of the ring formation which is integral with the arm 30 are provided with. apertures and the lugs at the ends'ofthe separable-portion of the ring formation are provided with: notches, as indicated at 44 in Figure fi. Screws 45' and 46 extend through the lugs on the twoportions of the ring formation a'ndar'e' provided with nuts 41 and 48 respectivelyto'secure the two portions of the ring formation together. r

In using thedevice, the wing' nut screw 20 is loosened*'andjthe hingemernber is adjusted relative to'fthe bracket i4-untiI-the' pointer '2'! imp icate the proper indication on the protractor scale 26 to -give the desired cutting angle on the pipe ,section to be cut. With the wing nut/50 on the screw3l loosened and the se arable portion 5! of the ring formationtz removed from the integral portion 52.9f' the ring formation, the base block in is set on the pipe section with its concave sidein firm contact with the pipe section. .Thepi'pe section will. be partly received in theintegralportion 52. of the ring formation and the, separable portion Elof the ring formation is nowconnected to the integral portion52 so that the pipe is entirely surrounded by the ring formation. :The bracket i4 is then adjusted along the standard I3 until the pipe is centered in the opening 4| of the ring formation, whereupon the wing nut 59 is tightened to secure the bracket in properly adjusted position.

A suitable marking instrument; such as a piece of chalk, may now be movedaround the smooth side of the ring formation'32 remote-from the base block In to provide 'a mark around the he on the 4 pipe which mark can be used for cutting the pipe so that the cut edge of the pipe will be in a plane disposed at the predetermined angle to the longitudinal center line of the pipe for which the gauge was set by the protractor scale 26.

The notches 44 in the lugs of the separable portion of the ring formation permit this portion to be removed from the integral portion of the ring formation without removing the screws 45 and 48 or the nuts 41 and 48, and'are so shaped as to render 'the'marki'ng side of the ring formations smooth and continuous when the two parts of the 'ring formation are secured together.

The qslidable connection between the stem 24 ment for the gauge which is particularly useful when, the arm 3ll-is set at a large angle to the standard I 3, in centering the ring formation relative'to the associated pipe section and the square shape of the standard l3 and stem 24 together with the complementary square shapes of the stem receiving portions of the bracket 14 and clamp 3! provide an instrument of high accuracy in which the parts are rigidly held in properly adjusted position relative to each other.

The gauge may be made in different sizes or different size arms and ring formations may be provided for pipes in different size ranges, but the instrument is so designed that each ring formation will accommodate a pipe size range of at least one inch in diameter. j

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof." The present embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, the scope ofthe invention being indicated by the appended claims rather than by'the foregoing description, and allohanges which come within the meaning 'and range of equivalency of the claims are, therefore, intended to be embraced therein.
